To (all rv/zom- 2'1 may concern-.-

Be it known that I, ()nn C. TRASK, a citizen of the United States, residing at T0- ronto, Ontario, Canada, have invented certain new and useful Improvementsin Steamlropelled Vehicles, of which the following is a specification, reference being had to the accompanying drawings. p

In the operation of automobiles, designed to be propelled by steam iorces, it is custrunary to provide a boiler under the hood of the automobile with burners thereunder -ltor heating the water contained in the boiler and thus generating the steam by which the vehicle is propelled. It sometimes happens that the burners so placed beneath the boiler tail to function properly or are left open so that gases gather:in the exhaust chambers of theboiler and should the operator attempt to ignite the burner while these gases are present, an explosion is very probable.

It is the prime object oi. my invention to provide means for quickly and positively removing these gases from the exhaust chambers as to dispense with the possibility of an explosion when the burner is ignited and live gases are contained in the exhaust chamber.

it is a further object of my invention to provide such a device of cheap and simple construction and which may be easily as sembled and used.

It is a further object of my invention to provide means for assisting in the condensation of the water in the radiator of the automobile which means are used in conjunction with the means for removing gases fromthe exhaust chamber of the boiler.

lVith these and other objects in view, my invention consists in the arrangement, combination and construction of the various parts of my improved device as described in my specification, claimed in my claims and shown in the accompanying drawings in which:

Fig. 1 is a plan view of an automobile with certain parts thereof cut away and showing improved device mounted thereon.

Fig. 2 is a detailed View showing the swinging doors mounted on the boiler and used in removing gases therefrom.

Fig. 3 is a detailed view showing certain features of the means for oprrating said doors.

trical wiringused in my iniproved"device.

Fig. 7 is a detaihd view showing an electrical connection made by the operation of certain parts of my improved device,

I have shown my improved device mounted upon a conventional. automobile having frame member 1, a dash 2, a steering column 3, a steering wheel a radiator 6.

The boiler 5 has disposed thereunder a burner "T from whichthe' flames 8 extend. Insulation 9 dispos d around the outer.

a steam boiler 53 and portion oi the boiler 5so as to prevent heat contained therein from radiating outwardly.

The exhaust fumes coming irom the flames 8 will be normally carried through thetubes 41 contained in the boiler 5 into the chamber 10 in the upper. part of the boiler 53 and thence out through the rear thereof as indicated by the arrows in l: g.

5. It oftentimes happens, however, mature burner 7 fails to function with the result that livegases will pass through the tubes 2 41-1 and gather in the chamber 10 and the tubes 4-1., Should the burner"? then be ignited, an explosion is very likely to occur.

The forward portion of the chamber 10 is provided witha pair of doors 11 and 12 which are pivotedat 13 and 14 respectively so that they may swing inwardly and thus open the chamber 10 at its forward end.

The doors 11 and 12 are adapted to he opens; and closed by pulling and pushing on the handle .15 of the rod 16 which latter rod is attached at its forward end to the bell crank 17 on one end of the pivot rod 14. A similar crank 18 is provided on the pivot pin 14: and attached to a rod 19 lead ing to a third crank 20 attached to the pivot pin 13.

I provide a fan 21 journalled on the shaft 22 and directly in the rear-of the radiator 6.

Also journalled'on the shaft 22 is an elec- 28 so that when the steam throttle rod the doors 11 and, 12 in the forward side of the chamber and at the same time closing I an electrical connection leading from the battery through the conductor 26 and the conductor 32 into the spring contact by reason of the contact therewith otthe member 34 on the rod 16W-l1i0l1 is constructed of conducting material so that the current willflow onthrough the conductor 35 and the conductor 30 into the motor 23 and back through the conductor 31 into the battery 25 and starting the motor 23 and the fan 21.

It will thus-be seen that the opening of; the doors 11 and '12 and the simultaneous starting of the fan 21 will cause ,a current of air to flow through thechamber 10 as indicated by the arrows in Fig. 5, thus clearing the same of any fumeswhich may be,

gathered therein and avoiding the possibility otan explosion.

Some changes may be made in the arrangement, combination and construction of the various parts of my improved mecha-- nism without departing from thespirit of my invention and it is-niy intention toicover by my claims such changes as, may be reasonably included Within the scope 40 thereof;

What I. claim is: V 1; In combination, a boiler having a burner thereunder for heating the same, a

chamber adapteditoreceive gases from said burner, a normally closed entrance into said chamberand means for opening said entrance, a fan adjacent said entrance wherebywhen said' entrance is opened and said fan is operated, gases Within said chamber thathave accumulatedfrom the use of the burner will be forced" out;

2; In combination, a boiler having a burner thereunder for heatin'gthe same, a

chamber, doors for: said chamber and said doors adapted'to be opened and closed by a rod extending" therefrom, a fan adjacentthereto .and adapted toforce the gases within said chamber therefrom when said doors are opened.

3; In combination, a boiler havingaburner' thereunder for heating the same, a chamber adapted toreceive gases from said burner, a'normally closed entrance into saidflchan ber, a fan adjacent said entrance and means for simultaneously opening said entrance and starting said fanwhereby gasesformed in said} chamber may be forced there-from;

4: In combination, av boiler having a burner thereunder for heating the same, .a-

chamber adapted to receive gases froin-saidburner, doors in said chamber adapted to be opened-and closed by a* rod extending therefrom, a an adjacent thereto adapted to be operated by electrical.,.power and means whereby; when said rod ismovcdto open said doorssaid fan will be started and force gases formed in sa d chambertherefrom.
